Comment:

 Ok some changes happened. I took over the branch as discussed and
 implemented a way to not trigger a new fetch request if we already have
 one pending for a given service.

 So, if we launch 7 SOCKS requests, the first one will fetch then the 6
 others will wait patiently that either the descriptor arrives or the
 fetches fail and they are all closed after.

 See branch: `bug23653_032_01`

 This does NOT implement the above for v2, only v3 for now. If we are
 satisfied with this, we should fix v2 for an improved user experience.
